WILLIAM S. KERN, OF WILKES-BARRE, PENNSYLVANIA.

MIXING AND STRAINING MACHINE.

Application filed September 10, 1906.

To all whom it may concern:

Be it known that 1, WILLIAM S. KERN, a citizen of the United States, residing at WVill-zesBarre, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Mixing and Straining Machines, of which the following is a specification, reference being had therein to the accompanying drawing.

The present invention relates to improvements in mixing and straining machines and has especial reference to machines for mixing and straining catchup, tomatoes, jellies, fruits, medical compounds, paints, soups, and the like, the object being to provide a means whereby various component parts of the mixture are thoroughly mixed and strained, the strained portion being received in one hopper while the coarser particles are separated therefrom and may be deposited in another hopper, the mixing means heing adapted to feed the mixture through the straining mechanism so that the liquid passes through the straining mechanism and the coarser particles pass out of the open end.

The invention can be best illustrated in connection with the accompanying drawings, of which Figure 1 is a side elevation of a machine for the purposes described. Fig. 2 is an end elevation thereof. Fig. 3 is a longitudinal section on the line x-sc of Fig. 2. Fig. 4 is a longitudinal section on the line yy of Fig. 2. Fig. 5 is a section of the straining mechanism taken on the line z2.of Fig. 3, looking in the direction of the arrows. hig. 6 is a perspective View of the movable portion of the apparatus. Fig. 7 is a detail view of one end of this movable portion, showing means for securing it upon its shaft. Fig. 8 is a sectional View of a hub for supporting the scrapers and brushes of the mixing mechanism, as will be hereinafter referred to. Fig. 9 is a view in end elevation of the head of the straining mechanism at that end at which the coarser particles are discharged; and Fig. 10 is a plan view of a detail showing the manner of securing the head shown in Fig. 9 in place upon the straining mechanism.

Referring to the drawings, the mechanism is mounted upon a support consisting of the standards 2 connected together at their lower ends by the transversely extending strips 3 and the longitudinally extending strip 1. These standards are connected together longitudinally by strips 4, while at one end the Specification of Letters Patent.

strips 5 and 6 extend transversely between them.

At the opposite end of the frame from the transverse strips referred to, metal casings 7 are secured and in these casings a cross-piece 3 is removably fastened by pivoted latches 9. Mounted upon the cross-pieces are bearings 10, 11, and 12, for the shaft 13 of the straining and mixing mechanism, and it will be obvious that by removing the cross piece 8 that mechanism can be removed endwise from the support. A pulley 14 for actuating the mechanism is secured to the shaft 13.

The mixing and straining mechanism comprises brushes and scrapers mounted upon the shaft 13 before referred to, a screen consisting of suitable perforated material such as wire gauze or netting being supported concentrically about the shaft 13 by suitable means, as will be hereinafter referred to.

To describe the specific construction of screen shown, and its su porting means, it comprises at one end a ead 24 having an opening 25 for the passage of the shaft 13 which is supported by means of the bracket 23. One end of the tapered or truncated cone-shaped screen is entered within the flange of this head and is secured thereto by the wedging action of a ring 30 between which and the flange of the head the end of the screen is pinched. At the other end of the strainer is a ring or band 31 having a shoulder formed thereon upon which one end of the straining gauze rests, the gauze being held in position by the wedging of the ring 31 within the end of the strainer so that the last is pinched between that ring and a ring 22 upon the outside of the gauze. To support and strengthen the strainer, the longitudinal rods 27 extend along the outside of the gauze and each is secured at one end of the ring 22 while the other end is secured to the ring 26 supported by the flanges of the head 24:. Fitted upon the ring 31 is a closed head having an opening for the passage of the shaft 13, which. opening allows vertical clearance for the shaft so that it may adjust itself to varying conditions of operations This head also comprises a spout or outlet 49 through which the coarse unstrained particles are discharged as they are delivered into the head of the strainer.

The end of the strainer opposite the bracket 23 rests upon a curved part 21 so that a substantially tight joint is secured,

this part 21 forming a portion of the hopper from the strainer as will be hereinafter referred to. The head just referred to, which is shown particularly in Fig. 9, and the ring- 31 by which it is carried are secured in place upon the strainer by means of perforated cars 32, extending from the ring 31, through which extend projections '33 mounted upon brackets 34 fixed to the support, the said projections being provided with notches adapted to be engaged by catches 36 pivoted upon projections 38 of the brackets 34.

Within the tapering strainer is mounted the means for mixing the material to be strained and forcing it through the screen. This means consists in paddles or scrapers 46, and brushes 45 usually mounted upon the ends of arms or spokes 43 secured by means of set screws to hubs 42 which in turn are secured upon a bushing 39 secured to the shaft 13 by means of a catch 41. Both the brushes and the paddles or scrapers extend longitudinally of the strainer and are so mounted as to be in contact with or close to the strainer throughout their lengths and during all their movements.

An inlet pipe 47 is provided for supplying the material to be strained to the mixing and straining apparatus, and if desired a valve 50, which may be automatic or manually o erated, may be employed for regulating to supply of material to the apparatus. The mouth of the supply pipe 47 is shown clearly as indicated by the reference numeral 48.

The strained material will be delivered throughout the length of the screen and for the purpose of catching this strained materia a hopper supported upon the frame is provided. This hopper extends at its upper end above the lowest point of the strainer and consists of a short rear wall 16, a downwardly inclined bottom 17, a front wall 20, and a bottom horizontal portion 18, and the curved portion 21 hereinbefore referred to. At the lowest portion of this hopper is a substantially hemispherical opening 19 from which leads a delivery pipe 53 which may be controlled by a suitable valve 54.

In the operation of the machine, the parts having been assembled as shown, the material to be mixed and strained will enter through the supply pipe 47 and opening 48 within the truncated cone-shaped screen at its small end. The axis of this screen being horizontal it will be apparent that the bottom of the screen Will be inclined towards the larger end at which the exit for the particles which ,do not pass through the screen is located. During the feeding of the material to the small end of the strainer, the brushes and paddles or scrapers will be rotated in such direction that the paddles will precede the brushes. The result is that the material will be thoroughly mixed and such portionsthereof as are capable of passing through the screen will be brushed through the same while the coarser particles which cannot pass through the screen will by reason of their continuous agitation by the brushes and paddles gravitate toward the larger end of the screen and pass out of the funnel 49 where any suitable disposition can be made of them.

Having thus described my invention, what I claim and desire to secure by Letters Patent, is

1. In a mixing and straining machine, the combination with a strainer having an inlet, adapted to receive material to be strained, at one end and an exit to discharge the unstrained material, at its otherend, of a brush and a paddle movably mounted so as to move over the surface of said strainer, and means for receiving the strained material.
